Efficient Image Transmission in Underwater Communication using OFDM Modulation

Abstract

This design describes the transmission of aquatic images over an OFDM system. Different modulation schemes are used to transmit images over wireless technology. Due to channel fading, only a subset of carriers can be used for successful data transmission in an OFDM system. Channel state information can be used at the transmitter to best match predictive decisions to reject image frames if they are DWT-compressed in use. Compressed data is uploaded to the OFDM system. Next, examine descriptions to the correct subcarriers and to make the individual shard channel status data available at the transmitter. This indicates that sub-channels are good or bad for ocean metamorphism via OFDM channels. The descriptors assigned to currently active channels are in descending order of priority based on the sender's 1-bit channel state information. Allocations to the problematic subchannels described are omitted in the transmitter to reduce system power consumption.
